Oliver Jäkel - Sysadmin - Securing all the Stuff

Hi, I'm Oliver Jäkel. I work in IT for about 25 years. I'm a Senior Security Consultant working at @HiSolutions. I'm specialized in Microsoft Technologies - but my Linux-Foo grows stronger every day. I love Powershell, Active Directory and I like to automate stuff. I like to look behind stuff, I wanna know what keeps these systems running and how they work.

I'm currently learning Azure Security and Python.

How to reach me: contact me via Twitter @JaekelEDV or

Hallo, ich bin Oliver Jäkel. Ich arbeite seit fast 25 Jahren in der IT. Ich bin Senior Security Consultant bei @HiSolutions. Ich bin in den Microsoft-Technologien zu Hause, aber meine Linux-Kenntnisse wachsen von Tag zu Tag. Ich liebe die PowerShell, Active Directory und mag es, alles zu automatisieren. Ich schaue gerne hinter die Kulissen. Ich will wissen, was die Systeme am Laufen hält und wie sie ticken.

Ich lerne gerade Azure Security und Python.

Zu erreichen bin ich gut über Twitter @JaekelEDV oder
